Passed out, low potassium,unexplained pain, high blood pressure- undiagnosed

56year old female, passed out and hospitalized. Went in to hospital and said had arterial fibrillation,low potassium, high blood pressure. Ran all tests, EKG,MRI,etc. Found no cause of passing out. Changed blood pressure medicine, took off diaretics. Having pain occur randomly in foot, goes away after few days, has reoccured now behind knee, painful and cannot walk on it. No explaination from Dr.'s. Liver blood test came back high, red blood count low, low iron. Also on Coumadin and blood pressure medicine, Coreg. Need to find out what direction to go with. Still not driving, due to unknown reason for passing out.

Atrial fib alone can make you pass out. With A-fib your heart does not have good blood output which in turn deprives your body including your brain of precious nutrients & oxygen. Low cardiac ouput also can cause hypotension (low blood pressure). Which can also make you pass out if you have a sudden significant drop in B/P.

Low potassium can cause heart irregularities such as A- fib. Diuretic depletes potassium & that is why it when potassium went low & your other problems spiraled from there.
Low iron can make you short of breath & fatigued. You could be bleeding slowly somewhere which could cause low iron (RBC'S) esp. seeing you are on Coumadin.

This should be investigated. Hopefully they are routinely checking your clotting levels.

Some meds can cause your liver enzymes to go up.

I take it Coreg is your new B/P medication. It can also cause dizziness when you first start taking it. This usually goes away with continued use.

I hope you start feeling better. Take it easy until your symptoms have subsided & you've had your follow up appointment with your physican.            Good Luck, J

Thank you for that info. I am a bit confused though. Two cardiologist told me that you cannot pass out from A-fib. I was not on Coumadin until after this incident. The Dr.'s will not clear me to drive, since they cannot pinpoint what happened. I have gone to Cardiologist, Neurologist and my regular Physician. I am just concerned that they cannot give me any anwers.
